Granted: 2011-09-20
Abstract: - Elle comporte la construction d'une chaîne de réalisations représentatives d'un modèle stochastique (Y) en combinant graduellement une réalisation initiale de (Y) et une ou plusieurs autre(s) réalisation(s) de (Y) dite composite(s) et l'on minimise une fonction objectif (J) mesurant l'écart entre un jeu de données non linéaires déduites de la dite combinaison au moyen d'un simulateur d'écoulement dans le milieu, et les dites données mesurées dans le milieu, par ajustement des coefficients de la combinaison. La réalisation composite résulte de la projection de la direction de descente de la fonction objectif, calculée par le simulateur d'écoulement pour la réalisation initiale, dans le sous-espace vectoriel engendré par P réalisations de (Y), tirées au hasard et indépendantes les unes des autres, ainsi que de la réalisation initiale. Durant le processus d'optimisation, la chaîne ainsi obtenue est explorée de façon à identifier une réalisation qui permet de minimiser la fonction objectif (J). Pour réduire suffisamment cette fonction objectif, on explore des chaînes construites les unes après les autres en prenant comme réalisation initiale la réalisation optimale déterminée pour la chaîne précédente. Applications notamment à l'exploitation de gisements pétroliers par exemple.

Title: Method and reactor for the non-thermal decomposition and pasteurization of organic process materials by electroporation
Inventor: SCHULTHEISS CHRISTOPH
IPC: A23L13/70
Filed: 2002-08-21
Granted: 2011-05-10
Abstract: According to the invention, in a reaction chamber, which constitutes a component of a process installation for obtaining foodstuffs or foodstuff components, biological products in harvested form that are whole or in pieces are subjected to pulsed electric fields as they traverse said chamber. Said electric fields form pores in the cell walls, i.e. irreversibly open the latter, thus making the cell contents more easily accessible. This is achieved by electrode groups, which can be impinged by a high voltage and are located in a longitudinal zone of the wall of the reactor zone along the traversing axis of the process material and by earthed electrodes located in an opposing longitudinal zone. Each electrode group is connected to a rapid electric energy accumulator, such as for example a Marx generator, by means of a switch, in order to rapidly establish electric fields of multiple directions between the electrodes that are to be currently charged and the earthed electrodes. There is only ever one group of electrodes at high voltage for a predetermined time period.

The piece of meat is allocated to one of a multiple of workstations, inasmuch as identification for the said workstation is registered and the allocated piece of meat is processed at the workstation while use is made of visual instruction.  Hereinafter, a further transport is established of the whole or parts of the yield from the cutting-up of the allocated piece of meat, such as one or more cuts. The further transport is similarly registered so that traceability is established for the pieces of meat.

Abstract: Each synchronous flow (i=1, 2, ..., Ns) is associated to a respective synchronous capacity value (Hi) that is related the period of time for which a synchronous flow can be serviced before the server moves on. This value can be selected either according to a local allocation criteria or according to a global allocation criteria. Each asynchronous flow (i=1, 2, ..., NA) s is associated to a respective first value indicating the delay to be made up so that the respective queue has the right to be serviced and to another value indicating the instant in which the server visited the respective queue in the previous cycle. Each queue associated to a synchronous flow (h) is then serviced for a period of time that is related to be aforesaid synchronous capacity value, while each queue associated to an asynchronous flow (i) is serviced only if the server's visit occurs before the expected moment. The server's visit (10) to the synchronous queues should preferably take place during two successive cycles in order to optimise the use of the resources available.
